Pilgrimage (S01E05)

Ichika and Rio embark on a school trip to Okinawa, where Masuda unexpectedly joins them, accompanied by a senior from his job who acts as their photographer. Throughout the trip, Rio shares pictures with Ryo, which stir up memories of Kai and leave him feeling anxious. In another turn of events, Ryo discovers an anime keychain that his coworker Matsushima Arie accidentally dropped. She requests that he keep her interests a secret from their colleagues, and Ryo responds with a thoughtful compliment in return.
